Cranston, B. 1., assignor to Universal Winding Company, Boston, Mass acorporation of Massachusetts Application July 3, 1945, Serial No.003,040 I 9 Claims. (Ci. 242 -43) and other strand materials in cops,cones and the like.

In the present specification and claims the term "yarn is used in ageneral sense to indicate any type of attenuated material and the wordpackage" is intended to designate the wound mass of yarn whatever itsform or shape.

One object of the invention is to provide a winding machine forproducing packages of yarn or the like with a so-called universal orprecision wind.

Another object is to provide a machine for winding yarn with a precisionwind while maintaining a uniform linear speed of draft on the materialdelivering to the package.

Another object is to provide a winding machine having a simplified formof traversing mechanism for distributing the yarn on the package bymeans of a traveler to eliminate the use of complicated and relativelyheavy reciprocating parts.

Another object is to provide a traversing mechanism for winding machinesin which the yarn is guided by a light-weight traveler oscillatedthrough direct engagement with a skeleton cam having a narrow helicalrim.

Another object is to provide a winding machine in which the strand ofyarn or the like feeds directly from the tension device through thetraveler to the winding package without diversion or abrupt bends in itscourse.

A further object consists in providing a winding machine having aminimum of moving parts and capable of operating at high speed withoutvibration and noise and with a reduced amount ofwear on the movingparts.

Further objects of the improvement are ,set forth in the followingspecification which describes a preferred form of construction of theinvention, by way of example, as illustrated by the accompanyingdrawings. In the drawings:

Fig. 5 is an end view looking in the same direction as that of Fig. 4and illustrating the gearcasing with its cover removed to disclose thegainer gearing, so-called, which is enclosed therein;

Fig. 6 is an enlarged perspective view of a modifled form of travelerfor traversing the yarn on the package; and

Fig. 7 is a detailed end view of the same.

In the usualtype of machines for winding yarn with a universal,precision or V-wind the winding spindle is driven positively at aconstant rate of speed to rotate the package and the yarn is traversedlengthwise of the spindle with the rate of draft of the yarn increasingprogressively as the packagev increases in diameter. In this type ofwinding machine the traversing thread-guide is reciprocated at a uniformrate, that is, in certain ratio to the speed of the winding spindleexcept for a slight increase therein to give an increment of motion tothe guide whereby it will lay the yarn in helical coils with each' coilin closely adjacent relation to the previously wound coil. With thistype of precision winding the package is built up with the turns orcoils in all of the layers extending from end to end of the package in apredetermined number of convolutions and crossing each other with asymmetrical V-shaped pattern on the surface of the package.

In another type of winding machine the package is driven at aprogressively diminishing rate of speed by means of a drum or drive-rollcontacting with the surface of the winding whereby v the draft ontheyarn is maintained constant as Fig. 1 is a side elevational view ofthe complete winding machine showing certain of its casings in sectionor as broken away to reveal the mechanism enclosed therein;

Fig. 2 is an end elevation of the machine showing the relationship ofthe parts at the start of winding a cop or package;

Fig. 3 is a similar end view showing the parts in the position whichthey assume at the completion of winding a package;

Fig. 4 is a part-sectional view looking in the opposite direction fromthat of Fig. 3 and showing the machine with certain of the partsremoved;

the package grows in size. In this latter type of winding the coils of.yarn are laid in more or less haphazard manner; that is, extending fromend to endof the package with a maximum number of convolutions at thestart of winding and decreasing to a minimum number at the completion ofthe package with the spacing between the coils increasing anddiminishing constantly throughout the winding. For most purposes the unijvers'al or precision wind is considered of evan ageyas producing amore stable and-superior forinfof package with a maximum amount ofyarncontained therein and capable of delivering with greater freedom undermore constant tension. It is therefore an object of the presentinvention to provide a machine for producing precision wound packageswhile at the same time maintaining a uniform draft on the yarndeliveringto the winding without increase in the tensipn thereon as thepackage grows in diameter. Referring first to Figs. 1 and 2 of thedrawings,

and pro died with suitable bearings for the variousrotating elements. Asshown more particuiarly in Fig. 1, the frame 2' is of substantiallyrectangular shape in side view comprising a base 4 with uprights 5 and 6rising therefrom for supporting a pair of bearings and 6' at-the top.

Journaled in the opposite bearings I and 8 is a winding spindle l6 whichprojects from one side of the frame 2 and carries a suitable packageorcop-holder H thereon. The cop-holder Il may be in the usual form of anexpansible mandrel for receiving a cylindrical paper tube t or it maytake the form of a truncated cone, not herein illustrated, when themachine is fitted for winding conical packages. chine the spindle i 6 isiournaled to rotate freely in its bearings 1 and 6 but is not connectedto be driven from the main source of power as is the usual arrangementin machines for producing packages with a precision wind. On thecontrary, the winding spindle i6 is adapted to bedriven from a drum ordrive-roll, indicated at II in the present drawings, which is mountedfor peripheral contact with the surface of the package being wound andarranged to move away from the spindle as the winding increases indiameter during the growth of the package.

As shown in Figs. 1, 2 and 3, the drum or driveroll i5 is mounted on ahorizontal shaft i6 journaledin bearings I! and i6 carried by a frame 26of inverted U-shape. The frame 26 is formed with opposite parallel arms2i and 22 which straddle the uprights 5 and 6 of the main frame 2 and[are pivoted on studs 23 and 24 screwed into the uprights. Thedrive-roll shaft I6 carries a series of integral sheaves or pulleys 25for receiving a belt 26 passing over one of a series of sheaves orpulleys 21 on the shaft of an electric motor 36. The electric motor 36is preferably mounted on the base 4 within the .sides of the frame 2and'suitably secured in place by bolts 3|. The series of pulleys 25 and21 are of graduated size and positioned in reverse order so that thebelt 26 may be shifted from one pulley to another to vary the speed ofthe shaft i6 and thereby the drive-roll different conditions of winding.

Pivota'lly mounted on the main frame 2 is a second bifurcated frame 32carrying bearings 33 and 34 for a horizontal shaft 35. The arms 36 and31 of the frame 32 are pivoted on the studs 23 and 24 which form thepivots for the frame 26. As shown in Fig. 1, the shaft projectsoutwardly beyond its bearing 34 on the frame 32 and carries a traversecam 46 on the opposite side of the winding spindle I6 from the driverolll5. The cam 46 is of skeleton construction comprising a hub 4| fast onthe shaft 35 with curved spokes, 43 radiating therefrom for sup-.porting the helical rim 45 of the cam. The

spokes 43 and rim 45 of the cam 46 are preferably constructed ofsheet-metal with the rim consisting of a relatively narrow stripencircling the hub 4i in helical configuration. The cam 46 may thus beof relatively light weight to reduce the effects of inertia and momentumwhen it is rotated with the shaft 35.

As shown more particularly in Figs. 2 and 3 the cam 46 is enclosed by acasing 46 of substantially cylindrical form mounted on the frame 32. Thecasing 45 may be mounted on a disk-like inner end plate 41" having anextension 46 bolted to the side of the arm 31 of the frame 32 at 46 Inthe present maand provided with a horizontal arm 56 extending laterallytherefrom. A second circular disk 5| is attached to a flange 52 at theend of the arm 56 by means of bolts 53 for cooperation with the innerdisk 41 to support the circular casing or :cover 46. The cover or casing46 consists of a strip of sheet metal bent into cylindrical form with agapbetween its horizontal edges, its circular edges being received inannular grooves 54' in the disks 4! and 5|. Preferably, the horizontaledges of the cover 46 are bent inwardly to lock in suitable depressionsin the grooves 54 to hold the cover from turning on the disks. Extendinglaterally IaCI'OSS thecasing thus formed and fastened to the end disks4! and SI is a horizontal bar 55 located within the gap between thehorizontal edges of the cover 46. The rod or bar 55 may be ofrectangular cross-section as shown in Fig. 2 to provide a support forthe traveler 66 I5 in accordance with to maintain the latter in oppositerelation to the winding spindle 16 while adapting it to slide back andforth therealong under the impulse of the cam 46.

The traveler 66 may be constructed of sheetmetal with a portion 6|overlying the top of the bar 55 and bifurcated to straddle the sides ofthe rim 45 of the cam 46 to connect it to be reciprocated therefrom. Anextension 62 reaches downwardly and then across the under side of thebar 55 and is continued in a downturned flange 63 which may be slottedor bifurcated to receive the strand of yarn y feeding therethrough tothe package. A modified form of traveler 65 may be constructed of wireas shown in Figs. 6 and 7 of the present drawings, one length 66 of thewire extending across the periphery of the rim 45 of the cam 46 andstraddling its edges with rearward curved portions 61 engaging its innerrim. The wire is then extended forwardly to overlie thetop of the bar 55with portions 66 bent inwardly and then down and outwardly, on theunderside of the bar with the ends curved outwardly to provide abifurcation or notch 16 for receiving the yarn 11.

It will be understood that the cam' 46 is mounted on the frame 32 toadapt it to move outwardly away from the winding spindle with the growthof the package P as indicated in Fig. 4. The swinging movement of theframe, 32 in this manner is caused by the movement of the drive-- rolll5 in the opposite direction and controlled by a connection between thetwo frames 26 and 32 to be described hereinafter. In order to effect asmooth even motion of the two frames 26 and 32 away from the windingspindle l6 suitable dogging means may be provided as next described. Inthe present embodiment of the invention the dogging means are mounted onthe frame 32, see Figs. 2 and 4, and adapted to cooperate with anarcuate quadrant 15, the dogging device being of usual constructionpreviously used in the art. The quadrant I5 is fastened at 16 to theinner side of the upright 6 of the frame 2 by a screw 11 and is formedon its under side with an arcuate tapered groove 16. The dog 86 may beconstructed of wire with a bent portion 6| pivoted in a hole in the arm31 of the frame 32 and an arm extending therefrom toward the quadrant 15with an arcuate extension 82 of wedge-shape in cross-section engaging inthe tapered groove I6 in the quadrant I5. A sheet-metal finger-lever 65enclosing the projecing end of the bent portion 8| of the dog 66 isclamped thereto by a screw 66 to provide for manuahoperation of the dog36-to release it from the quadrant 15. The dog 66 a spur gear 99 whichwith the surface of the winding between said member is normallymaintained in binding engagement with the quadrant to resist movement ofthe frame 32 in counterclockwise direction, in Fig. 4, by means to theupper end of the finger-lever 95 with its end bearing againsta'projecting plate 99 constructed integral with the end disk H, seeFigs. 1 and 2. y

As has been stated, the winding spindle I9 is driven from the drive-rollI5 through the contact of the roll with the yarn on the winding packageand in order that the traverse cam 49 may be rotated in proper speedratio with that of the spindle it is driven therefrom. Referringparticularly to Figs. 1 and 5, the winding spindle I9 carries in thegainer casing 92. The gear 99 meshes with a gear 93 which, in turn,meshes with a gear 94 engaging another gear 95. The gear 95 carries acompanion gear 99 fast therewith which meshes with a larger gear 91 on astub-shaft 99 iournaled in a bearing 99 on the casing 92. On theopposite endof the stub-shaft 99 is a sprocket-wheel I99 which isconnected by a chain IN to a sprocket I92 fast on the cam-shaft 35. Thegears 94, 95 and .95 are mounted to adapt them to be interchanged withother gears of different size whereby to permit varying the ratiobetween the speed of the winding spindle I9 and that of the came shaft35; this being the conventional arrangement as previously used in theart for adjusting the speed ratio between two shafts or other rotatingelements. This type of fixed gainer gearing being well known to thoseversed in the art, it will not be described more specifically herein. Asshown in Figs. 1 and 5 the gainer casing 92 is supported on an extensionI93 of the main frame 2 and secured thereto by bolts I94. To give accessto the gears in the casing 92 a cover I95 is removably mounted acrossits opening, being held at the bottom in a ledge I95 and fastened at thetop by a latch-spring I91.

The frame '29 which carries the shaft I9 and drive-roll I5 is maintainedwith the roll in contact by means of shown in weights I99 suspended froma strap H9 Figs. 1 2 and 3. The strap H9 is fastened to the frame 29 atIII and thence passes over a grooved pulley I I2 journaled on the innerface of the upright 9 of the main frame 2. The strap II9 depends throughopenings in the base 4 of the frame 2 and the top of the table or bed 3and carries a rod I It at its end supporting a plurality of the weightsI99. The weights I99 can be added to or subtracted from to adjust thepressure of the drive-roll I5 against the surface of the package beingwound.

The means for effecting proportional receding movement of the drive-rollI5 and cam 49 consists in a connection between the arms of the frames 29and as a part of the arm 31 of the frame 32 is a curved arm or extensionII9 provided with an arcuate slot I29. A similar curved arm or memberI2I is connected to the arm 22 of the frame 29, being formed with anarcuate slot I22 curved in the opposite direction from that of the slotI29 on the frame 32. The member I2 I is pivoted on the stud 24 whichforms the pivot for the frame 29 and is connected to the arm 22 of saidframe by means of a, bolt I23 passing through a slot I24 in the armwhereby to provide for relative adjustment and the frame 29. A pair inthe arcuate slots I29 and of rollers I25 engaging I22 are journaled on astud I29 formed with a as viewed of a leaf-spring 91 fastened drives atrain of gearing 32 as next described. Formed.

flange or head I21 which is adapted to slide in a vertical slot I29 onthe outer face of the upright 9 of the frame 2. The flange or head I21on the stud I29 engages grooves I29 in the sides of the slot I29 to holdthe stud in place and the outer end of the stud may be riveted over toprevent displacement of the rollers therefrom.

-' During the operation of the machine the frame 29 is swung inclockwise direction, as viewed in Figs. 2 and 3, as the drive-roll I5recedes from the winding spindle I9 during the growth in the winding andthe rollers I25 will travel in the arcuate slots I29 and I22. Therollers I25 will be caused to move in a vertical path as guided by thesliding movement of the stud I29 in the slot I29. During this verticalmovement of the stud I25 the rollers I25 will act between the two slotsI29 and 122 to cause the frame 32 to move by and with the movement ofthe frame 29, that is, in the opposite or counterclockwise direction asviewed in Fig. 3. The curved member I2I on the frame thereto to causethe frame 32 to move at such a rate that the traveler 99 which forms theguiding The relative movement of the two frames 29 and 32 is describedmore in detail in connection with the explanation of the operation ofthe complete machine.

P The operation of the machine is controlled by suitable stopping andstarting mechanisms which may be of any conventional type as well knownto those versed in the art. For starting the winding operation ahand-lever I49 is mounted at the top of the main frame 2, being -securedto a rock-shaft I4I shown in Fig. 1. This lever I49 may be arranged toclose a switch in the circuit for the electric motor 39 or it may beconnected to actuate suitable clutch-means to start the rotation of thedrive-roll shaft 35. Suffice it to state that the lever I49 has a curvedarm or extension I42, shown by dotted lines in Fig. 3, formed with ashouldered detent I43 at its end which is engageable with a similardetentslioulder I44 on an arm I45 to maintain the.

,A usual form of tension-device i59 is mounted on an arm I 5I attachedto the side of the frame 2 and adapted to apply a uniform tension to thestrand 1/ .as it. feeds to the windingijpackage, this part of themachine being of conventional construction forming no part of thepresent invention and therefore requiring no further description herein.Suflice it to state that the yarn 1/ is drawn upwardly from its sourceof supply, not shown, threaded through'the tension-device I59, thenceled to the cop-tube t on the winding spindle I9 and its end securedthereto to start the winding of a package. The method of operation ofthe machine during the progress of the winding is explained as follows:

To start the operation of themachine the lever I49 15 swung into theposition shown in Fig. 2 to engage the detents I43 and I44, see Fig. 4,whereby to cause the drive-roll shaft I9 to be driven from the motor 39or through any other 29 may be adjusted in relation the bolt I23 andslot connection with a source of power. Before starting the machine thedrive-roll l must be placed with its periphery in contactwith thesurface of the cop-tube t mounted on the cop-holder II; this beingaccomplished by releasing the dog 80 and swinging the frame 32 inclockwise direction to cause the frame 20 to be moved in the oppositedirection to bring it into the position shown in Fig. 2. As the frame 32is thu moved to swing the frame 20 and set the drive-roll I5 inoperative contact with the cop-tube t the traverse cam 40 will becarried into close association with the periphery of the cop-tube. Asbefore stated, the frame 32 carrying the'cam 40 may be set initially insuch position that the traveler 60 wllleither contact with the yarn onthe package during the winding or be spaced at a slight distancetherefrom; this being accomplished by properly adjusting therelationship between the curved arms H9 and I2I through the mean of I24in the arm 22 of the frame 20, see Fig. 2.

As the drive-roll I5 is driven from the motor 30 its contact with thecop-tube it will rotate the winding spindle ID to cause the yarn to becoiled on the tube. Meanwhile, the cam 40 will be driven from thewinding spindle through the driving connections at the opposite end ofthe machine. That is, the gear 90 on the winding spindle III will drivethrough the gears 93, 94, 85, 96 and 91 to rotate the stub-shaft 98 andthereby the sprocket I 00 to impart its rotation through the chain IM tothe sprocket I02 on the end of the cam-shaft 35. The cam 40 thus will berotated to impart reciprocating motion to the traveler 60 to cause theyarn strand 1! to be traversed back and forth longitudinally of thecop-tube t on the winding spindle I0, The traveler 60 will slide backand forthon the horizontal bar 55 and thereby be guided in a horizontalpath parallel with the axis of the winding spindle I0; although it hasbeen determined that the horizontal guiding means for the traveler isnot essential. That is to say, if the traveler 60 is allowed to bearagainst the surface of the winding the rotation of the winding spindlein the direction indicated by the arrow in Fig. 2 will tend to hold itin definite relation with respect to the spindle without the use ofv anytrack or guide therefor.

As the yarn feeds to the winding spindle I0 drawing through thetension-device I 50 tension is applied thereto to insure that the coilsof yarn will be deposited in place with the layers firmly compacted toproduce a stable package containing a maximum amount of yarn in a givenspace. As the yarn is traversed backand forth by the reciprocation ofthe traveler 60 it will be laid in helical coils extending from end toend of the package P being wound and disposed in precise relationshipforming a definite pattern on the surface of the winding. Due to thefact that the traverse cam 40 is driven directly from the windingspindle III the ratio of speed between these two elements is maintainedsubstantially constant so that the package will be wound with a uniformnumber of turn in each layer. The mass of yarn being wound on thespindle I0 constantly increases in diameter during the winding andconsequently the speed of the winding spindle I0 is progressivelydiminished from start to finish of the package. Therefore, since thedrive-roll I5 is rotated at a uniform speed and the package driventherefrom through peripheral contact therewith there will be no increasein the rate of sion applied thereto as in the slots I20 and I22 8drafton the yarn being fed to the package. This is an importantconsideration since in most machines for producing packages with theUniversal or V-wlnd the winding spindle is driven positively andconsequently the linear speed of the yarn increases progressively withthe increase in circumference of the package. Due to this usual methodof operation means must be provided for gradually relieving the tensionon the yarn delivering to the package which results in complication ofthe mechanism of the machine. For many types of material it is tain auniform speed of draft of the yarn during the winding of the package soas not to submit the yarn to undue strain or abrading action, while atthe same time providing fora maximum rate of production in the machine.The present invention provides this and other improvements as has beenset forth in the objects stated in the first part of the specification.

It is to be further observed that due to the fact that the yarn y feedsdirectly through the traveler 60 toward the top of the package P as thlatter .rotates in the direction indicated'by the arrow in'Figs. 2 and3, it is relieved of any undue tenby diverting its course in abruptbends. Consequently, delicate materials may be handled without unduestrain and without abrading or roughening the surface of the yarn. Ithas been stated that the speed ratio between the winding spindle and thetraverse cam remains substantially constant, but it should be explainedthat the cam is preferably driven with a slight gain to impart an addedincrement of motion to the reciprocating traveler 60. This isaccomplished through the use of suitable gainer gearing in the casing92, the object being to cause each coil of yarn to be laid at the sideof the previously laid coil in close juxtaposition thereto. This is awell known feature of the Universal or precision method of windingwhereof the coils of yarn are prevented from being disposed one on topof another during the building of a package.

As the package continues to wind on the cop- 'tube t to form overlyinglayers of crossing coils the increase in diameter of the mass will causethe drive-roll I5 to be forced'outwardly away from the winding spindlein the manner indicated in Fig. 3 of the drawings. movement of thedrive-roll I5 with respect to the winding spindle III the frame 20 isrocked or swung in clockwise direction as viewed in Fig. 3, therebycausing the rollers I25 to ride upwardly of the arms or members I I 9and I2 I, respectively, as the stud I25 is guided upwardly in thevertical slot I28. The movement of the roller I 25 in the slot I 20 ofthe curved arm H9 has the effect to rock the frame 32 incounterclockwise direction, as viewed in Fig. 3, to cause the traversecam 40 to recede from the winding spindle III with a rate of motioncommensurate with that of the drive-roll I5. As has been explained. thecurved arm I2I is adjustable on the frame 20 by means of the bolt I23 inthe slot I 24 and thereby the relationship between the two arms ormembers H9 and I 2| may be regulated so that the traverse cam 40 will bemoved at the same rate as the roll I5 and in conformity withthe growthof the winding package. If desired. the initial setting of the curvedarm I 2| may be such that the traveler 60 is caused to reof advantage tomain- During this receding maintained constantly in contact with thesurface of the winding under the pressure created by the weight I09suspended by the strap III) to act on the frame 20. As before noted, thedog 80 carried by the frame 32 is caused to slide in the groove 18 ofthe quadrant 15 as the two frames 20 and 32 swing away from the windingspindle l0. Any tendency for the frames and the parts carried thereby tovibrate or rebound'as they are being forced outwardly by the windingpackage is prevented by the binding of the tapered extension 82 of thedog 80 in the groove 18 of the quadrant.

After the package P has been completed to the required size thedrive-roll l and traveler 60 may be moved away from its surface byswingin .the frame 32 outwardly so that the package may be withdrawnfrom the winding spindle It). To recommence the winding operation it isonly necessary to place a new cop-tube t on the spindle 10, attach theend of the yarn y thereto, return the drive-roll l5 into contact withthe surface of the cop-tube and cause the yarn to be inserted. in thecentral notch or opening in the traveler 60. The machine is then startedto operate by energizing the motor 30 or connecting suitableclutch-mechanism on the drive-roll shaft l5 through the medium of thehand-lever I40.

It will be observed from the foregoing description that the presentinvention provides an improved winding machine for producing packages ofyarn or the like with a precision wind while maintaining a uniform speedof draft, of the yarn throughout the winding. The improved machine is ofsimple construction and arrangement embodying a minimum number of movingparts with elimination of the usual eating traverse-bars and othermoving of relatively great weight.
